See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h) ^2 - k = 0, the vertex is (h, - k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2) ^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1) ^2 = 2
(x - 1) ^2 - 2 = 0
The vertex is (1, - 2)
